Fig. 7From: Assessing the criteria for definition of perimembranous ventricular septal defects in light of the search for consensusThe images show a perimembranous defect opening to the right ventricular inlet in the setting of malalignment between the atrial septum and the crest of the muscular ventricular septum, which is marked by the red dotted lines. The left panel shows the view from the right ventricle, with the right panel showing the left ventricular view. There is straddling and overriding of the tricuspid valveBack to article page
